The director presents the strategic report for the year ended 30 November 2025.

The year ended 30 November 2025 was another period of significant growth and strong profitability for the company.

Turnover increased by 29.9% from £12.26 million to £15.92 million, driven primarily by increased levels of remediation activity across the company's project portfolio. Revenue from remediation works increased to £15.07 million compared with £11.32 million in the previous year.

Gross profit increased from £4.92 million to £7.11 million, with the gross profit margin improving from 40.1% to 44.6%.

Operating profit increased by 44.3% to £6.68 million (2024: £4.63 million), reflecting strong project delivery and effective management of direct operating costs.

Profit before taxation increased to £6.68 million (2024: £4.63 million), while profit after taxation increased by 44.2% to £4.99 million (2024: £3.46 million).

The company continued to generate strong cash flows during the year, with cash balances increasing to £2.86 million at the year end from £1.87 million in the prior year. Net assets increased to £3.80 million (2024: £0.91 million), despite dividends of £2.10 million being paid during the year.

The company also invested significantly in operational plant and equipment during the year, with capital expenditure totalling £282,551, supporting future growth and operational capability.

The company operates within the environmental remediation sector and is subject to a range of commercial and operational risks. The principal risks identified by management include:

• Changes in construction, development and environmental market activity that could affect demand for remediation services.

• Availability and cost of specialist subcontractors, plant and equipment.

• Compliance with environmental, health and safety, and waste management regulations.

• Credit risk arising from customer balances and project-related receivables.

• Dependence on maintaining strong relationships with key customers, suppliers and group companies.

Management monitors these risks regularly and seeks to mitigate them through careful project selection, robust commercial controls and active cash flow management.

The company focuses on the following as KPI's:

Turnover        £15.92m        £12.26m

Gross Profit    £7.11m        £4.92m

GP Margin    44.6%        40.1%

Profit after tax    £4.99m        £3.46m

Cash at bank    £2.86m        £1.87m

The board remains positive regarding the outlook for the business. The company enters the new financial year with a strong balance sheet, healthy cash reserves and an established reputation within its sector.

Management will continue to focus on profitable growth, operational efficiency and investment in equipment and resources that support the delivery of remediation projects. While economic and sector-specific uncertainties remain, the director believes the company is well positioned to capitalise on opportunities within the remediation and environmental services market.

On behalf of the board

The director presents his annual report and financial statements for the year ended 30 November 2025.

The principal activity of the company continued to be that of remediation activities and other waste management services.

The results for the year are set out on page 8.

Ordinary dividends were paid amounting to £2,097,000. The director does not recommend payment of a further dividend.

The director who held office during the year and up to the date of signature of the financial statements was as follows:

So far as each person who was a director at the date of approving this report is aware, there is no relevant audit information of which the company’s auditor is unaware. Additionally, the directors individually have taken all the necessary steps that they ought to have taken as directors in order to make themselves aware of all relevant audit information and to establish that the company’s auditor is aware of that information.

This report has been prepared in accordance with the provisions applicable to companies entitled to the medium-sized companies exemption.

The director is responsible for preparing the annual report and the financial statements in accordance with applicable law and regulations.

Company law requires the director to prepare financial statements for each financial year. Under that law the director has elected to prepare the financial statements in accordance with United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law). Under company law, the director must not approve the financial statements unless he is satisfied that they give a true and fair view of the state of affairs of the company and of the profit or loss of the company for that period.

In preparing these financial statements, the director is required to:

• select suitable accounting policies and then apply them consistently;

• make judgements and accounting estimates that are reasonable and prudent; and

• prepare the financial statements on the going concern basis unless it is inappropriate to presume that the company will continue in business.

The director is responsible for keeping adequate accounting records that are sufficient to show and explain the company’s transactions and disclose with reasonable accuracy at any time the financial position of the company and enable them to ensure that the financial statements comply with the Companies Act 2006. He is also responsible for safeguarding the assets of the company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

We have audited the financial statements of Rock Remediation Limited (the 'company') for the year ended 30 November 2025 which comprise the statement of comprehensive income, the balance sheet, the statement of changes in equity and notes to the financial statements, including significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:

• give a true and fair view of the state of the company's affairs as at 30 November 2025 and of its profit for the year then ended;

• have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and

• have been prepared in accordance with the requirements of the Companies Act 2006.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor's responsibilities for the audit of the financial statements section of our report. We are independent of the company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the director's use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

Our responsibilities and the responsibilities of the director with respect to going concern are described in the relevant sections of this report.

Other information

The other information comprises the information included in the annual report other than the financial statements and our auditor's report thereon. The director is responsible for the other information contained within the annual report. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of our audit:

• the information given in the strategic report and the director's report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

• the strategic report and the director's report have been prepared in accordance with applicable legal requirements.

In the light of the knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in the strategic report or the director's report.

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:

• adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or

• the financial statements are not in agreement with the accounting records and returns; or

• certain disclosures of director's remuneration specified by law are not made; or

• we have not received all the information and explanations we require for our audit.

As explained more fully in the director's responsibilities statement, the director is responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the director determines is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the director is responsible for assessing the company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the director either intends to liquidate the company or to cease operations, or has no realistic alternative but to do so.

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes our opinion. Reasonable assurance is a high level of assurance but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

The extent to which our procedures are capable of detecting irregularities, including fraud, is detailed below.

We assessed the nature of the company's activities as a provider of remediation activities and waste management services, its control environment and business performance, and considered where the financial statements may be susceptible to material misstatement due to fraud or error. Our approach included discussions within the audit engagement team regarding how and where fraud might occur in the financial statements, including consideration of the risk of management override of controls and the risk of inappropriate revenue recognition. The key laws and regulations considered relevant to the company included the Companies Act 2006, UK taxation legislation, health and safety legislation, environmental and waste management regulations and employment legislation.

Our procedures included enquiries of management regarding any actual, suspected or alleged fraud, and any known instances of non-compliance with laws and regulations. We considered the responses received in conjunction with our understanding of the company and the results of     other audit procedures performed.

Our procedures to address the risks identified included:

• Enquiries of management regarding any known or suspected instances of fraud or non-compliance with laws and regulations;

• Reviewing relevant records and supporting documentation where available;

• Testing journal entries and other adjustments for evidence of management override of controls;

• Performing substantive procedures over revenue recognition, including testing samples of revenue recorded in the accounting records to supporting documentation and related cash receipts;

• Testing significant balance sheet balances, including trade debtors, cash balances, amounts due from and to group undertakings, taxation balances and other material estimates and judgements; and

• Reviewing management's assessment of the company's ability to continue as a going concern, including consideration of available financial information, post year-end performance and the assumptions used by management.

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements. This risk is greater in relation to irregularities arising from fraud than from error, as fraud may involve deliberate concealment, collusion, forgery, intentional omissions, misrepresentations or the override of internal controls. The further removed non-compliance with laws and regulations is from the events and transactions reflected in the financial statements, the less likely our audit procedures are to identify it. Our audit procedures were designed to identify material misstatements in the financial statements rather than to identify all instances of fraud or non-compliance with laws and regulations.

A further description of our responsibilities is available on the Financial Reporting Council’s website at: https://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor's report.

Other matters which we are required to address

The corresponding figures for the year ended 30 November 2024 have not been audited. Accordingly, we do not express an audit opinion or any form of assurance on those corresponding figures.

Use of our report

This report is made solely to the company's member in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the company's member those matters we are required to state to the member in an auditor's report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company's member, for our audit work, for this report, or for the opinions we have formed.

The profit and loss account has been prepared on the basis that all operations are continuing operations.

These financial statements have been prepared in accordance with the provisions relating to medium-sized companies.

Rock Remediation Limited is a private company limited by shares incorporated in England and Wales. The registered office is Unit 1a Vale Business Park, Langar Road, Barnstone, Nottinghamshire, United Kingdom, NG13 9GH.

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006.

The financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest £.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

This company is a qualifying entity for the purposes of FRS 102, being a member of a group where the parent of that group prepares publicly available consolidated financial statements, including this company, which are intended to give a true and fair view of the assets, liabilities, financial position and profit or loss of the group. The company has therefore taken advantage of exemptions from the following disclosure requirements:

• Section 7 ‘Statement of Cash Flows’: Presentation of a statement of cash flow and related notes and disclosures;

• Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instrument Issues: Interest income/expense and net gains/losses for financial instruments not measured at fair value; basis of determining fair values; details of collateral, loan defaults or breaches, details of hedges, hedging fair value changes recognised in profit or loss and in other comprehensive income;

• Section 26 ‘Share based Payment’: Share-based payment expense charged to profit or loss, reconciliation of opening and closing number and weighted average exercise price of share options, how the fair value of options granted was measured, measurement and carrying amount of liabilities for cash-settled share-based payments, explanation of modifications to arrangements;

• Section 33 ‘Related Party Disclosures’: Compensation for key management personnel.

The financial statements of the company are consolidated in the financial statements of Western Rock Holdings Ltd. These consolidated financial statements are available from Cabourn House, Station Street, Bingham, Nottinghamshire, NG13 8AQ.

Turnover is recognised at the fair value of the consideration received or receivable for goods and services provided in the normal course of business, and is shown net of VAT and other sales related taxes. The fair value of consideration takes into account trade discounts, settlement discounts and volume rebates.

For long term contracts, income is recognised based on the level of practical completion attained, which is determined based on valuations performed. Contracts are broken down sufficiently to allow the directors, with reasonable certainty, to assess the level of profitability associated with them. Provision is made for losses on all long terms contracts as soon as such losses become apparent.

Tangible fixed assets are initially measured at cost and subsequently measured at cost or valuation, net of depreciation and any impairment losses.

Depreciation is recognised so as to write off the cost or valuation of assets less their residual values over their useful lives on the following bases:

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is credited or charged to profit or loss.

At each reporting period end date, the company reviews the carrying amounts of its tangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

Cash and cash equivalents are basic financial assets and include cash in hand, deposits held at call with banks, other short-term liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities.

The company has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102 to all of its financial instruments.

Financial instruments are recognised in the company's balance sheet when the company becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset, with the net amounts presented in the financial statements, when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

Basic financial assets, which include debtors and cash and bank balances, are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of the future receipts discounted at a market rate of interest. Financial assets classified as receivable within one year are not amortised.

Other financial assets, including investments in equity instruments which are not subsidiaries, associates or joint ventures, are initially measured at fair value, which is normally the transaction price. Such assets are subsequently carried at fair value and the changes in fair value are recognised in profit or loss, except that investments in equity instruments that are not publicly traded and whose fair values cannot be measured reliably are measured at cost less impairment.

Financial assets, other than those held at fair value through profit and loss, are assessed for indicators of impairment at each reporting end date.

Financial assets are impaired where there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows have been affected. If an asset is impaired, the impairment loss is the difference between the carrying amount and the present value of the estimated cash flows discounted at the asset’s original effective interest rate. The impairment loss is recognised in profit or loss.

If there is a decrease in the impairment loss arising from an event occurring after the impairment was recognised, the impairment is reversed. The reversal is such that the current carrying amount does not exceed what the carrying amount would have been, had the impairment not previously been recognised. The impairment reversal is recognised in profit or loss.

Financial assets are derecognised only when the contractual rights to the cash flows from the asset expire or are settled, or when the company transfers the financial asset and substantially all the risks and rewards of ownership to another entity, or if some significant risks and rewards of ownership are retained but control of the asset has transferred to another party that is able to sell the asset in its entirety to an unrelated third party.

Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An equity instrument is any contract that evidences a residual interest in the assets of the company after deducting all of its liabilities.

Basic financial liabilities, including creditors, bank loans, loans from fellow group companies and preference shares that are classified as debt, are initially recognised at transaction price unless the arrangement constitutes a financing transaction, where the debt instrument is measured at the present value of the future payments discounted at a market rate of interest. Financial liabilities classified as payable within one year are not amortised.

Debt instruments are subsequently carried at amortised cost, using the effective interest rate method.

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Amounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities. Trade creditors are recognised initially at transaction price and subsequently measured at amortised cost using the effective interest method.

Derivatives, including interest rate swaps and forward foreign exchange contracts, are not basic financial instruments. Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. Changes in the fair value of derivatives are recognised in profit or loss in finance costs or finance income as appropriate, unless hedge accounting is applied and the hedge is a cash flow hedge.

Debt instruments that do not meet the conditions in FRS 102 paragraph 11.9 are subsequently measured at fair value through profit or loss. Debt instruments may be designated as being measured at fair value through profit or loss to eliminate or reduce an accounting mismatch or if the instruments are measured and their performance evaluated on a fair value basis in accordance with a documented risk management or investment strategy.

Financial liabilities are derecognised when the company’s contractual obligations expire or are discharged or cancelled.

The tax expense represents the sum of the tax currently payable and deferred tax.

The tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported in the profit and loss account because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

Deferred tax liabilities are generally recognised for all timing differences and deferred tax assets are recognised to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Such assets and liabilities are not recognised if the timing difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit.

The carrying amount of deferred tax assets is reviewed at each reporting end date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised. Deferred tax is charged or credited in the profit and loss account, except when it relates to items charged or credited directly to equity, in which case the deferred tax is also dealt with in equity. Deferred tax assets and liabilities are offset when the company has a legally enforceable right to offset current tax assets and liabilities and the deferred tax assets and liabilities relate to taxes levied by the same tax authority.

Payments to defined contribution retirement benefit schemes are charged as an expense as they fall due.

Rentals payable under operating leases, including any lease incentives received, are charged to profit or loss on a straight line basis over the term of the relevant lease except where another more systematic basis is more representative of the time pattern in which economic benefits from the leases asset are consumed.

Transactions in currencies other than pounds sterling are recorded at the rates of exchange prevailing at the dates of the transactions. At each reporting end date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the reporting end date. Gains and losses arising on translation in the period are included in profit or loss.

In the application of the company’s accounting policies, the director is required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

The average monthly number of persons (including directors) employed by the company during the year was:

Their aggregate remuneration comprised:

The actual charge for the year can be reconciled to the expected charge for the year based on the profit or loss and the standard rate of tax as follows:

The following are the major deferred tax liabilities and assets recognised by the company and movements thereon:

The deferred tax liability set out above relates to accelerated capital allowances. No material reversal of this liability is expected in the next 12 months.

The company operates a defined contribution pension scheme for all qualifying employees. The assets of the scheme are held separately from those of the company in an independently administered fund.

During the year the company entered into the following transactions with related parties:

All balances are interest free and repayable on normal invoice terms where invoiced, or on demand for other monies borrowed/lent.

The following amounts were outstanding at the reporting end date:

All balances are interest free and repayable on normal invoice terms where invoiced, or on demand for other monies borrowed/lent.

During the year an advance of £100,276 (2024: £nil) was made to a director. No amounts were written off or waived. At the year end an amount of £99,766 (2024: £510 owed to director) was due from the director. Interest has been charged at the official rate.

The company's immediate and ultimate parent undertaking is Western Rock Holdings Limited, a company incorporated in England and Wales. The ultimate controlling party is the Kane family by virtue of shareholdings in the parent company.
